How to change SID on Windows system using sysprep?

This article let you know how to change SID on Windows system using Sysprep, we just test it on Windows 10, Windows 7, and Windows Server 2008, it is same on other Windows system. I see many of you are looking how to change SID using NewSID, but New SID is not officially supported by Microsoft. You could use NewSID on Windows Server 2008, but when you try to use it on Windows Server 2008 R2 it won’t work, actually, it will “destroy” operating system. My advice is to use Sysprep. Changing SID using Sysprep is also very simple, just follow few steps as described below…

First, Press Win+R key at the same time to open the Run, type Sysprep and press OK.

Sysprep can be located in this directory C:\Windows\System32\Sysprep.

This will open the System Preparation Tool 3.14 window. As a System Cleanup Action select Enter System Out-of-Box Experience (OOBE). Important: select Generalize if you want to change SID, it’s not selected by default. As Shutdown Options select Reboot.

It will take some time for Sysprep to finish, so grab a cup of coffee and wait.

After rebooting you’ll have to enter some data, for example, Country or region, Time and currency, and Keyboard input.

Also, you’ll have to accept EULA. And that’s it. After booting, in Server Manager you’ll see that everything is changed, if you had some settings set now they’re changed.

Now you can again use PsGetSid to check that your OS has new SID.
